An attacker must transform an SMI to a more complex one to trigger this issue. Successful exploitation may allow remote attackers to obtain root access on an affected system.
In the following example, an attacker sends an SMI to an affected system. If the system receives this SMI and responds with a function pointer, the system may cause a stack-based buffer overflow. SMI to SMI - Stack Overflow In the following example, an attacker sends an SMI to an affected system. If the system receives this SMI and responds with a function pointer, the system may cause a stack-based buffer overflow. Dell BIOS contains an SMI to SMI - Stack Overflow vulnerable.

Vulnerability Discoveries:
What Can You Do?
One of the most important aspects of vulnerability discovery is to find the appropriate vendor. This will help you get an understanding of the severity of the issue and prevent it from going unnoticed. The following are some steps that can help you find a vendor:
1) Searching for affected systems on your local network 2) Searching for affected systems on public networks 3) Searching for affected systems on national networks 4) Searching for vulnerable firmware or hardware devices 5) Searching in vulnerability databases, such as CVE If a system has been compromised, then it is vital to investigate it immediately.
